The presentinventionrelates to a printing device, and'more particularly to a printing device especially adapted for use in marking machines. V v

Infthe present type of marking machines now in use for printingprice tags, pin tickets and the like, itis customary to use a type chase wherein the type is changed for each new run of tags or tickets. In cases where it may be desirable to print a thousand or more tickets with identical indicia, such'type changing is not a serious burdenIBut where, as is more often the case, it is-d'esired to'pr'int a short run of say ten to one hundred tickets with one setting, and then another short run with another setting, it is obvious 'that'much time 'will be lost in resetting type for eachrunof tickets to be printed.

It is an object of the invention to provide a printing device wherein a plurality of relatively thin diskscarrying a" set of type are placed face to face on a shaft so that the type at the portion of thedisks presented to the ticket to be printed are close together, so that a large number of characters maybe printed on very small tickets. Another object of the invention is the provision of means for quickly and easily adjusting the type carrying disks to bringthe desired type characters to printing position.

Another object of the invention is the provision of novel means of removably holding the type in said disks so that worn out type may be readily replaced.

'Other objects and advantages of the present invention will appear hereinafter.

" A preferred embodiment of the invention selected for purposes or illustration is shown in Figure 6 is a fragmentary detail in cross section through somev of the disk showing them in a position where one piece of type may be removed,and igure 'Tis a view similar to Figure 6 showing a piece of type being removed.

'Referring to the drawings, the device comprises a series of concentric type carrying disks arranged in'face to face relation, here shown eight in number, and referred to by the reference characters H, 52; i3;-|4;-l-5,- I6, I1 and I8. Each of'thetype"carr in -disks lfl to is i secured to one of a series of concentric or telescopic bushings H to H3, respectively, the four right hand disks being secured to bushings which extend to the right, and the four left hand disks being secured to bushings which extend to the left.

All of the type carrying disks H to t8 and their respective telescopic bushings I l' to 8 are rotatably mounted on a stationary shaft !9 which may be mounted on the frame of the marking machine frame in an suitable manner.

Each of the bushings II to [8 carries a pinion H" to Is" which may be formed integrally therewith, as shown, or may be secured thereto in any suitable manner. Said pinions H to [8 mesh with gears H' to I8" mounted on a second stationary shaft 20 running parallel to the shaft 19 and mounted on the frame of the machine in any suitable manner.

Each of the gears H to 18 carries a segment 2|, rigidly secured thereto by smallbrackets 22, and each of said segments is marked with a series of indicia corresponding to and arranged in the same order as the characters of the type carried by the respective disks. Each of the seg ments 2|, in turn is provided with an ear 23 by means of which the segments and gears may be manipulated as hereinafter described. A plate 24 may also be attached to any convenient part of the frame 25 of the machine, which said plate extends across the segments 2| and is provided with a series of windows 26 registering with the indicia on the segments, each of said windowsv being of a size to expose a single character of said indicia to the operator. The position of the segments and the position of the windows in the plate are adjusted, of course, so that the character on any segment which is exposed through its respective window corresponds to the face of the piece of type which is in printing position. 7

It will be observed that the pieces of type 21 are equally spaced around the periphery of the disks II to I8, the size of the disks being such as to permit carrying the number of type required for printing purposes with adequate spacing between type. The size of the pinions is so chosen as to permit all of the type carried by any disk to be brought to printing position with a limited motion of its corresponding segment 2|.

From the foregoing, it will be seen that the operator, before beginning a run of tickets, has merely to adjust the segments by manipulation of the ears 23 to expose the desired characters of a single line of type through the series of windows 26. When the segments are so adjusted, the corresponding pieces of type will be in printing position to cooperate with the platen P. The platen may befixed, in which case the entire printing head assembly may .be reciprocated for printing but I prefer to keep the printing head near the periphery thereof.

asmpos stationary and to reciprocate the platen as indicated in Figure 3. The type may be inked in any suitable manner, but I prefer to use an ink ribbon (not shown) which may be fed between the printing head and the platen in any suitable manner.

In the ordinary operation of the disksthe friction between adjacent disks and their respective bushings, as held on the shaft l9 by the collars 31 and 32, is sufiicient to retainthem in any po sition in which they may be set. However, if desired, suitable spring detents may be provided for this purpose.

In spite of the fact that the above described arrangement permits selective setting of the disks to bring any desired combination of type to printing position, so that the type may be set merely by rotating the disks as described, it is nevertheless important to permit individual pieces of type to be changed quickly and easily whenever necessary, as when a piece of type is broken or when certain pieces which are used more .frequently than others become worn.

Referring to Figures 4, 5, Sand '7, it will be seen that each piece :of type 21 is carried in a radial groove 28 formed. in one face of the disk, each groove having an undercut shoulder 29 to cooperate with the shoulder 29 on the type piece to hold the typ firmly against longitudinal movement in the groove. Since the disks are arranged face to face, the type in each disk is held against .sidewise motion by the abutting face of the next adjacent disk, except in the case of thedisk it, in which case the type is held by the thin nonty-pe carrying disk 39.

Each of the disks l2 to i8 is provided with a single groove 33 terminating in a slot at. extend- .ing clear through the entire thickness of the disk A flat spring 35 held in the groove 33 by a rivet '35 with the free end of the spring projecting into the slot 3 3 and bearing against the face of the next adjacent disk. Thus as the disks are rotated relative to one another in ordinary use the springs 35 prevent the pieces of type from falling out, of the grooves 28 as they pass the slots 34. However, whenever it is desired to remove and replace a certain piece of type in a certain disk, it is only necessary to rotate the next adjacent disk until its slot 3'4 is opposite the groove 28 carrying the piece to be replaced as shown in Figures 5, -6 and 7. ihen by tilting the piece :of type as shown in Figure 7, it may be easily removed and a new pieceiinserted in its place.

From the foregoing it will be seen that it is not necessary to: provide a slot 3 in the disk H, since the typ carried by disk M will be removed and inserted through slot 34 in disk l2. With respect "to the disk 58, however, the same result may-he accomplished by slitting. the disk 32 to provide a peripheral slot 3? ordinarily closed by spring finger 38 which ordinarily holds the type in. place, but may be bent outwardly to permit type to be removed from and inserted in the disk l8.

The portion of each of the disks where the slot 3 2. isv formed be used, of course, as a blank places where no printing is desired.

It will be understood that the invention may bewarieusly modified and embodied. within, the scope of the subjoined claims.
